Answer:
a. quantum computing and telecommunications
Explanation:
Both quantum computing and telecommunications need materials with specific optical, electrical, and magnetic properties to advance, and nanotechnologies open the opportunity for nanomaterial with incredible properties. From antennas with special magnetic properties to faster optical fiber from more stable material to store qubits to super thermal insulators, nanotechnologies will change the way we build and design telecommunication systems, and it will allow us to build stable and reliable quantum computers.
Answer:
There are two customers in the PostalCode.
SQL statement for select all the fields and the rows from the Customers table where PostalCode is 44000.
SELECT * FROM Customers WHERE PostalCode = "44000";
Explanation:

Answer:
(i) When transmitting a draft manuscript for a book, the lossless compression technique is most suitable because after decompression, the data is rebuilt and restored in its form as it was from where it originated
(ii) When transmitting a video recording which you have made of the school play, a lossy compression technique is most suitable because the large size of video files require the increased data carrying capacity which is provided by the lossy transmission technique. The quality of the video can be reduced without affecting the message intended to be delivered
Explanation:
Answer:
Relationship vs N-ary Relationship
Explanation:
It is not part of the design choice in ER model because N-ary reflects an indefinite form or better still creates an identifying attribute in an ER relationship. Example is the process of creating an auto-generated ID value
